@araichyk If this PR looks alright to you, I can go ahead and merge it.

Can't seem to reproduce the original issue for whatever reason. This change is hiding/unhiding the Publish button for me based on access level though.

Do we also want to remove the Publish link from this alert on TagEdit, TriggerEdit, and VariableEdit?

@araichyk Good point, will remove the link too :+1:

Aside from the broken UI test cases, the changes look good to me :+1:
